Custom Split Range Zero (CST ZERO)
It is used to set the current corresponding to the zeropoint when the valve position of 0 to 100% is
controlled by the user-set CUSTOM. For example, if the valve is controlled by 6-20 mA instead of 4-
20 mA, CST ZERO is 6 mA. However, the difference of the current between the origin point and the
endpoint must be greater than 4 mA.
